The following tips are intended to reduce the stress put on our visual
system during common day-to-day activities. They can be helpful for both
children and adults. Just like bathing and brushing teeth can lead to good
personal hygiene, following these tips can lead to good visual hygiene.
Keep reading material at the best distance
Reading, writing or close-up work is best done at a distance equal to
the length between the knuckles and the elbow. To determine this distance,
place knuckles under chin and book under elbow.
Look up occasionally when reading
To reduce eye strain when working on the computer or reading, look up
every eight to ten minutes and focus on different objects across the room.
Your eye does less work when focusing across the room, so looking up from
time to time from your reading can help keep your eyes relaxed.
Use good posture when reading or working on the computer
Good posture while reading, studying, or working on the computer helps
reduce eyestrain. Try to avoid reading while laying on your back, stomach,
or side.
Use good lighting
Make sure that there is good light on close work tasks and good general
room light as well. Illumination should be positioned so as to avoid glare
from your reading material. A light positioned behind and over ones shoulder
works well for reading.
Positioning your reading material optimally
Tilt your book so that it is raised up about 20 degrees from the desk.
This positioning aids in achieving good posture and reducing eyestrain.
Television
Most adults sit away from the television. Kids often need to be reminded
to sit at least 6 to 8 feet away from the screen to reduce eyestrain. Good
posture can aid in reducing eyestrain even while watching television.
Computer workstation set up
All of the tips
mentioned so far become doubly important if you spend a significant amount
of time working on the computer. Computer work can be even more stressful
on the eyes than regular reading or studying. The diagram below depicts
a workstation layout that provides good posture and optimal positioning
of the computer screen and reading material.
Glare on the screen can be a significant source of eyestrain. Setting up the computer so that it is out of direct sunlight and room light works
best. Breaks while working on the computer become even more important.
Combine looking up from your work with a short stretch.
